This, my darling, is where you have it wrong. Because what you think about yourself extends into how the world sees you.

Don't think nice lingerie is powerful? Imagine how you feel in a pair of cotton granny panties or a worn out bra with the underwire poking through . . . not so stellar, right? Now, imagine how you feel in something pretty and lacy . . . MUCH better!

There's a disconnect in your brain if you save your pretty things exclusively for special occasions. (It's like telling yourself that you only deserve to feel fantastic once in a while.) Here are four reasons you SHOULD definitely invest in (and regularly wear) pretty, sexy undies:

1. What you wear affects your confidence and self-esteem

The goal, after all, is to impress yourself. When you impress yourself, you'll automatically impress others. Experts found that wearing a Superman T-shirt under clothes made wearers feel more confident; that translates to the bras and panties you choose. When a woman wears lovely undies on a daily basis, she always feels beautiful and confident.

Pro Tip: Buy a variety of colors and styles of bras and panties so that on any day, you can choose what fits your mood!

2. A properly-sized bra makes your clothing fit better

Dozens of surveys show that as many as 80% of women are wearing the wrong size bra. If you haven't been fitted in the last year, it's time — go to a good store and get sized. Choose a bra that fits well and supports those beautiful boobs of yours. Surprisingly, the right bra can even make the rest of you look slimmer and more put-together.

3. Pretty underthings make you feel feminine

We live in such a masculine world, so even if you have to show that side of yourself at work (suits, slacks, jackets, etc.), wearing lovely lingerie underneath lets you embrace the power of femininity. I know it isn't as smoothing as those T-shirt bras, but there’s something magical about a lacy bra that makes you feel feminine and sexy. When you feel feminine, you tap into that magnetic feminine power of yours (and others will pick up on that radiated sexual confidence, girl).

Pro Tip: Lace bras are easier to wash and last longer than the molded bras — bonus! If you're larger than a D-cup, look for a lined lace bra.

Choosing to wear panties that match your bra is a secret that only you know, yet makes you feel powerful. Why? Underwear is what we wear closest to our skin, so choosing what feels beautiful sends a signal to your brain that you deserve beauty in your life. Also, we live in a masculine world, so even if you have to show that side of yourself at work (suits, slacks, jackets, etc.), wearing lovely lingerie underneath lets you embrace (and balance) your feminine energy. And a woman who owns both sides of her power and energy is a force to be reckoned with.

If you can’t stand the thought of lacey undies, matching a basic black or nude bra to basic black or nude panties is just as powerful and sexy as lacy underwear. Just give it a try. I’ll bet you notice the difference in how you feel.

Pro Tip: To keep your lingerie wardrobe in order, shoot for three pairs of panties per bra. Also, even though stockings aren’t necessarily in style, if they make you feel more powerful, wear them anyway!

By wearing and carefully selecting gorgeous lingerie every day, you develop a better sense of balance — a more conscious life.

Plus, it's like a delicious secret that you can choose to reveal . . . or not.

There's something about a sexy secret that makes you feel more alive. No matter what you're wearing on the outside, wearing beautiful lingerie underneath it all invigorates you.

It's time to fall in love with your life and yourself by choosing to dress with love and care. So, indulge in some sexy new undies, my dear ... because you are totally worth it.
